Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-12739 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2019-12739/ (Markdown: https://insights.sbomify.com/CVE-2019-12739/index.md)","id":"CVE-2019-12739","markdown":"https://insights.sbomify.com/CVE-2019-12739/index.md","name":"CVE-2019-12739","record":{"aliases":["CVE-2019-5441","GHSA-vpwh-6v3v-q9vw"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Nextcloud Extract add-on","requires_auth":"low_privilege","summary":"Remote attackers can execute arbitrary code on Nextcloud servers by injecting shell metacharacters into RAR filenames processed by the Extract add-on.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"extract","vendor":"nextcloud"}],"cvss":{"score":9,"severity":"critical","source":"cna","vector":"CVSS:3.0/AC:L/AV:N/A:H/C:H/I:H/PR:L/S:C/UI:R","version":"3.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"lib/Controller/ExtractionController.php in the Extract add-on before 1.2.0 for Nextcloud allows Remote Code Execution via shell metacharacters in a RAR filename via ajax/extractRar.php (nameOfFile and directory parameters).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Command injection in n/a","id":"CVE-2019-12739","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site Scripting in HAPI FHIR","id":"CVE-2019-12741"},"packages":[],"prev":{"headline":"Weak cryptography in n/a","id":"CVE-2019-12737"},"products":["n/a"],"published":"2019-06-05","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code on Nextcloud servers by injecting shell metacharacters into RAR filenames processed by the Extract add-on.","url":"https://insights.sbomify.com/CVE-2019-12739/"}
